At the same time, the temperature cannot be well controlled during the manual grinding and polishing processes. Excessive or long-term operation will cause the temperature to be too high, thereby affecting the hardness, strength, and durability of the structure. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1 to 4 , a first specific embodiment of the present utility model provides an inner cylinder stretching and shaping device, which includes a fixed frame 1, a lower pressing die 2 movably connected to the top surface of the fixed frame 1, and a forming die head 3 movably connected to the bottom of the lower pressing die 2. The lower pressing die 2 includes a water storage tank 4 and a lower pressing rod 5 fixedly connected to the bottom of the water storage tank 4. A spray hole 33 is provided on the bottom surface of the forming die head 3. A die head positioning hole 11 is provided at the middle position of the top surface of the fixed frame 1. The bottom end of the lower pressing rod 5 extends into the forming die head 3 and then passes through the die head positioning hole 11 and enters the fixed frame 1. After the forming die head 3 is connected to the bottom of the lower pressing die 2, it can enter the inner cylinder through the die head positioning hole to perform stretching and shaping treatment on its inner wall. The operation is simple and portable. That is to say, when the lower pressing die 2 presses down, it will drive the forming die head 3 to move downward on the inner wall of the inner cylinder. Friction occurs between the outer wall of the forming die head 3 and the inner wall of the inner cylinder, so that the inner wall of the inner cylinder is polished and polished, that is, stretching and shaping treatment, so that the surface of the inner wall of the inner cylinder remains uniform and flat. Such an operation is simple and portable, and can ensure the flatness and uniformity of the inner wall of the inner cylinder;

[0024] At the same time, a water storage tank 4 is provided in the lower pressing die 2. During the pressing process, the water in the water storage tank 4 can pass through the lower pressing rod 5 and enter the forming die head 3, and then be sprayed onto the inner wall of the inner cylinder from the spray hole 33 on the surface of the forming die head 3. On the one hand, it can help reduce the temperature of the inner wall surface of the inner cylinder, effectively cool the cylinder, and prevent excessive temperature rise during the stretching and shaping process, which affects the structural hardness, strength and durability of the inner cylinder. On the other hand, the water vapor can form a water film on the surface of the inner wall of the inner cylinder, which helps to reduce the frictional resistance, ensure the smooth pressing of the lower pressing die and the forming die head, and ensure the smooth progress of the stretching and shaping process.

[0025] Furthermore, during the process of the lower pressing die driving the forming die head to press down, the sprayed water vapor can also effectively reduce the dust generated during the friction process, ensure a clean treatment environment, and reduce environmental pollution.

[0026] The water storage tank 4 includes a water trough 41, a water pump 42 fixed at the bottom edge of the water storage tank 4, a delivery pipe 43 fixed at the top of the water pump 42 and connecting the water trough 41 and the water pump 42, and a water outlet pipe 44 fixed on the right side of the water pump 42. The water outlet pipe 44 runs through the inside of the lower pressure rod 5 and extends to the inside of the forming die 3. When the lower pressure mold 2 drives the forming die 3 to enter the inner wall of the inner cylinder, the water pump 42 extracts water from the water trough 41 through the delivery pipe 43 and enters the water outlet pipe 44. The extracted water is transported to the forming die 3 through the water outlet pipe 44, and then sprayed onto the inner wall of the inner cylinder through the spray holes 33 on the surface of the forming die 3, so as to provide water vapor support for the lower pressure mold 2 and the forming die 3 to perform stretching and shaping treatment on the inner wall of the inner cylinder, help cool the inner cylinder, and help effectively control the temperature during the treatment process to avoid excessive temperature rise of the material during the treatment process, which will affect the strength and durability of the structure.

A cylinder clearance hole 13 is arranged in the middle of the cylinder fixing plate 12. The fixing frame 1 is mainly used to place the inner cylinder. The bottom end of the inner cylinder to be processed is placed on the cylinder fixing plate 12. The cylinder clearance hole 13 on the cylinder fixing plate 12 is used to fix the bottom end of the inner cylinder. At the same time, the die head clearance hole 11 at the top of the fixing frame 1 can fix the top end of the inner cylinder, so that the inner cylinder The cylinder is fixed in the fixing frame 1, and the forming die head 3 enters the inner cylinder through the die head clearance hole 11, and its outer surface will fit closely with the inner wall of the inner cylinder. When the forming die head 3 moves downward, it will generate friction with the inner wall of the inner cylinder, which can rub the inner wall of the inner cylinder flat. The forming die head 3 moves downward along the inner wall of the inner cylinder, and finally falls onto the shockproof pad through the cylinder clearance hole 13. The shockproof pad 14 can provide a buffering force to avoid collision and wear of the forming die head 3, thereby extending the service life of the forming die head 3;

[0028] Furthermore, the front opening of the fixing frame 1 can facilitate the placement and removal of the inner cylinder and the forming die head 3, making the operation more portable and efficient.

A handle 31 is provided at one end of the plane, and a lower pressure rod positioning groove 32 is provided in the middle of the top surface. The protruding part of the molding die 3 enters downward into the die clearance hole 11, which can achieve stable positioning, thereby ensuring the flatness and uniformity of the inner wall of the inner cylinder. The operator can take and place the molding die 3 through the handle 31, and the operation is simple and fast. In addition, the stable positioning of the molding die 3 cooperates with the downward movement of the lower pressure mold 2, which can help reduce errors and reduce the unevenness or unevenness of the inner wall of the inner cylinder caused by errors.

[0030] The inner diameter of the positioning groove 31 of the pressing rod is equal to the outer diameter of the pressing rod 5. The inner diameter of the die head positioning hole 11 is equal to the maximum outer diameter of the forming die head 3, which is equal to the inner diameter of the cylinder barrel relief hole 13 and the inner diameter of the inner cylinder barrel 6. The pressing rod 5 is precisely fixed on the forming die head 3, and the forming die head 3 is closely attached to the inner wall of the inner cylinder barrel, ensuring the stability and accuracy of the downward pressing of the pressing die, and at the same time ensuring the accuracy and stability of the stretching and shaping process, thereby ensuring the flatness and uniformity of the inner wall of the inner cylinder barrel.

[0031] Working principle: During use, first align one end of the inner cylinder barrel 6 with the cylinder barrel relief hole 13 on the cylinder barrel fixing plate 12, and align the other end of the inner cylinder barrel with the die head positioning hole 11 at the top of the fixing frame 1, so as to fix the inner cylinder barrel 6 on the fixing frame 1. Then, insert the bottom end of the pressing rod 5 on the pressing die 2 into the positioning groove 31 of the forming die head 3 to fix the pressing die 2 and the forming die head 3. Then, place the outwardly protruding end of the forming die head 3 into the die head positioning hole 11 at the top of the fixing frame 1. The forming die head 3 can enter the inner cylinder barrel 6. Press down the pressing die 2, and the pressing die 2 will drive the forming die head 3 to move downward in the inner cylinder barrel 6. The outer wall of the forming die head 3 is closely attached to and rubs against the inside of the inner cylinder barrel 6 to perform stretching and shaping treatment on the inner wall of the inner cylinder barrel 6;
